Intuitive circuit breaker system

Power feed-in modules

Power feed-in modules Power feed-in modules

The brain of the system is the power module which can be interfaced via various communication protocols. The standard power module monitors trip status and provides remote reset for tripped circuits. The PROFINET power modules interface with devices at the cabinet and enable remote access to the device data. Remote capabilities make this system easy to monitor and easy perform maintenance from anywhere.

1- and 4-channel circuit breaker modules

1- and 4-channel circuit breaker modules

1-channel modules are available with fixed and adjustable nominal currents, and 4-channel modules are available with adjustable nominal currents. The nominal current of individual channels can be adjusted remotely using the online interface or manually via the LED push-button operation.

2-channel circuit breaker modules

2-channel circuit breaker modules

The 2-channel modules allow you to easily read off the set nominal current directly on the device at any time. These modules can be individually adjusted from2 to 10A or 1 to 4A on the NEC Class 2 versions. Both are equipped with active current limitation to ensure a more efficient utilization of the upstream power supply. The active current limitation restricts short circuit and overload currents to a value that is 1.5 to 2 times the nominal current. This protects the power supply against excessively high currents and prevents output voltage dips.

0 V distribution modules

0 V distribution modules

The 0 V distribution modules are an ideal addition alongside every circuit breaker module. They allow the 0 V potential to be fed back directly via the CAPAROC system. The return conductor from every protected circuit can be conveniently connected in the system. Separate terminal blocks for 0 V distribution are no longer necessary. Blue color-coded pushers make it easy to differentiate between the 0 V and 24 V potentials.

Current rail

Current rail

The current rail ensures the safe and uninterrupted supply of power to the modules. Perform maintenance work at any time without interrupting operation. Unplugging individual modules only removes power to those modules. The rest of the system continues to operate and does not shut down. The CAPAROC system can be extended at any time to meet the needs of your application.

 Configurator

Configurator Configure your customized circuit breaker system according to your demands.

The online configurator helps you design an overcurrent protection system that precisely meets your needs. Each project contains a 3D model, detailed bill of materials, data sheet, and a unique solution ID, making it possible to re-enter the project to make changes or additions.

Remote and manual configuration and reset

Manual configuration
The orange nominal current assistant dials on the 2-channel modules allow load currents to be manually adjusted from 2 to 10A or 1 to 4A on the NEC Class 2 versions. The nominal current of the 1- and 4-channel modules are adjusted using single push-button operation.
Electronic interlock setting protection
CAPAROC is equipped with an electronic interlock for protecting nominal current settings. The set currents can be locked remotely or via the PWR LED button on the power module. By pressing the button and briefly holding it down, changes to the setting on the module are blocked.
Remote access/reset using the PROFINET power module
The power module with PROFINET interface provides you with remote access to all device data and allows you to perform remote diagnostics and maintenance. With remote access, you can adjust or lock the individual channel current settings, turn them on/off, and even read the current flow.

The power module with PROFINET interface provides you with remote access to all device data and allows you to perform remote diagnostics and maintenance. With remote access, you can adjust or lock the individual channel current settings, turn them on/off, and even read the current flow.
Transparent operating state
Multi-colored LEDs ensure that the system state is transparent. Each circuit breaker module has one status LED per channel to indicate the current operating state of each channel.

The circuit breaker modules in the CAPAROC system are intuitive and easy to configure. The nominal current of each individual channel can be manually or remotely programmed or reset. The tri-colored LEDs indicate the operating state of each channel. The remote diagnostics and ability to remote reset increases safety and helps reduce downtime with easy maintenance from anywhere.

Create customized protection from the versatile options of the CAPAROC modular system with data-driven power modules to help you design an intelligent system. Select various circuit breaker modules based on features including cascaded channel start-up, intelligent tripping, active current limitation, and intelligent load shedding.

Each CAPAROC system can be easily upgraded with the PROFINET power module, so you can conveniently program, monitor, and view your system’s data from the power supply to the load. CAPAROC is also compatible with PLCnext Technology when using the PROFINET power module. The web interface provides a complete overview of system status and data to make changes easily.

Reliably supply and distribute power

Power distribution via current rail
The current rails connect the power module with every single module in the system. By connecting the supply line for positive and negative to the power module, the current rails are also supplied directly. You can swap out modules or perform maintenance and the rest of the system remains powered without downtime.
Expand your system
The structure of a CAPAROC system starts with the installation of an initial current rail with 8 or 20 slots. The individual modules are plugged onto the current rail and snapped into place. The system can be expanded with extension rails without the need for tools.
Easy power distribution
Power distribution modules allow the 0 V potential to be fed back directly via the CAPAROC system, decreasing wiring time and eliminating the need for additional terminal blocks. The blue color-coded pushers make it easy to differentiate between the 0 V and 24 V potentials.

Current rails are the elementary blocks of the CAPAROC system. They ensure the uninterruptible supply of power to all the modules in the system. Modules can be added or removed easily without downtime. The distribution modules are the perfect addition alongside every circuit breaker module for the 0 V load return. You can also easily distribute power and eliminate the need for 24 V fuses and additional terminal blocks.
